all whom it may concern:

Be it known that I, VVILLLAM D. PARK, a itizen of the United States, residing at hiladelphia, in the county of Philadelphia lIlCl State of Pennsylvania, have invented ertain new and useful Improvements in Atachments for Picker-Sticks, of which the ollowing is a specification.

My invention relates to an improved atachment for picker sticks, the object of the nvention being to provide improved means f this character which will permit quick adustment of the lug strap relative to the icker stick.

A further object is to provide an improveent of this character, which can be cheaply anufactured, readily applied, and will erve as an adjustable mounting for the lug tralp to regulate the stroke of the picker tic WVith these and other objects in view, the nvention consists in certain novel features f construction, and combinations and arangements of parts as will be more fully ereinafter described and pointed out in the laims.

In the accompanying drawings, Figure 1, s an edge view illustrating my improveents. Fig. 2, is a face view. Fig. 3, is a )erspective View of the attachment removed, nd Fig. 4, is a view in cross section on the ine 4 4 of Fig. 3.

1 represents an ordinary picker stick havng a bearing or fulcrumed upon a journal in 2, the latter supported in a suitable rame or bar 3.

& represents my improved attachment, vhich constitutes a bar adapted to rest gainst the picker stick, and having rounded nlargements 5 as clearly shown, to receive he lug strap 6 between them, and this lug trap as is ordinarily the case, straddles the icker stick and serves to oscillate the latter. The bar 4 is provided with longitudinal arallel grooves 6 to receive the parallel nds 7 of an adjusting member 8. This adusting member comprises a single strong ire coiled between its ends as shown at 9, 0 form a bearing on the journal pin 2, and he ends of the wire extend parallel as shown t 7, and are tightly clamped in the grooves Specification of Letters Patent.

WILLIAIVI D. PARK, OF PHILADELPHIA, PENNSYLVANIA:

ATTACHMENT FOR PICKERi-STICKS.

Patented Nov. 2, 1909.

Application filed March 9, 1909. Serial No. 482,280.

6 by means of a cross bar 10. This cross bar is provided with a central opening to accommodate a threaded bolt 11, the latter having its head countersunk in the inner face of the bar 4, and lock nuts 12 screwed on to its other end against a washer 13, to tightly clamp the cross bar down upon the wires 7 and secure the member 8 at any adjustment relative to bar 4:.

The ends of the bar 10 are preferably bent down against the side edges of the bar 4; as shown at 14 in Figs. 3 and 4, so as to hold the bar against turning movement.

It will thus be observed that by loosening the nuts 12, members t and 8 can be adjusted relative to each other, and by this means the position of the lug strap may be adjusted relative to the ournal 2 pivoting the picker stick, and hence the stroke of the picker stick can be varied by this adjustment to suit any and all conditions.

A great many slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not restrictmyself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. An attachment of the character described, comprising two members, one memclamping said clamping bar against said wires, whereby the members may be secured at various adjustments relative to each other.

2. In combination with a picker stick journal pin, a picker stick journaled thereon, an attachment comprisin a bar and a wire bent between its ends forming a coil to receive said journal pin, and having its ends extended parallel to each other, means for clamping the ends of said Wires at various adjustments relative to said bar, and a lug strap guide on said bar, and a lug strap straddling said bar and the picker stick, and located in said guide.

In testimony whereof I have signed my name to this specification in the presence of two subscrlbing Witnesses.
